ROAD-BUILDING AND BITCH-CLEANING MACL HINE.

Application filed May 20, 1922. Serial No. 562,311.

T 0 all whom it may concern:

Be it known that I, GEORGE A. STEvENs, a citizen of the United States, and a resident of R-ingwood, in the county of McHenry and State of Illinois, have invented a new and Improved Road-Building and Ditch-Gleam ing Machine, of which the following is a full, clear, and exact description.

This invention relates to improvements in road building and ditch cleaning machines, an object of the invention being to provide an apparatus which when drawn over a road or ditch, will give the proper pitch or crown to the road or angle to the ditch, and which is capable of adj ustments in accordance with the work to be done.

.A further object is to' provide a machine of the character stated which will be comparatively simple in construction, which will ble of wide range of adjustment to perform the desired functions, and which is oomp'aratively cheap to manufacture. V I l/Vith these and similar objects in view, the invention consists in certain novel features of construction and combinations, and arrangement of-parts, as'will be more fully hereinafter described and pointed out in the claims. In the accompanying drawings my improved machine.

Figure 2 is a fragmentary view in rear elevation of Figure showing the scraper frames in different po sitions.

Figure 4 is an enlarged view in section on the line Jr-'4. of Figure 3.

55, of Figure 4.

Figure 6 is a fragmentary view in section on the line 66 of Figure 3.

l and 2 represents the two sections of my improved main frame A. These sections 1 and 2 are of general rectangular form com prising crossed bars rigidly secured together and at their inner ends having bearings 3 for the reception of a rodor hinge pin 1,

which permits the sections 1 and 2 to assume a desired angular disposition I relative to each other, giving the necessary'pitch or crownin road building, but it is to be un- Figure 1 is a top plan view illustrating Figure 3 is a view similar to Figure 1 Figure 5 is a fragmentary view on the line "derstood of course, that any suitable means may be provided for rigidly securing the sections if desired.

B andC represent scraper frames. These frames B and ,C, are also composed of crossed bars rigidly secured together and of general oblongshape, and are provided on their longitudinal members with bolts 5,

which are projected through concentrically curved slots 6, in segments? which are rigidly fixed to the frame sections 1 and 2, and nuts 8, are screwed onto said bolts 5 to clampthe frames Band C in anydesired position of adjustment.

In full lines and dotted lines in Figures 1 and 3,1 indicate various positions of the scraper frames B and 0 relative to main frame A, and it is obvious that these scraper frames will be positioned in accordance with the work to be done. Each scraper frame B and C is provided witha longitudinally .positioned scraper blade 9 reinforced by angle bars 10 and provided at their ends with trunnions 11, mounted in bearings '12 in the ends of the scraper frames. Levers 13, are

rigidly secured at their lower ends to the angle bars 10, pivotally connected as shown at 14, at a point between their ends to cross bars 15 of the frames B and C, and are held in any position of adjustment bymeans of pins 16, whlch are projected through the leversand positioned in any of the series of openings 17 in segments 18 fixed to the frames B and C.

.It will thus be noted, that by moving the levers 13, the angular disposition of the scraper blades can be varied and rigidly held in such position by means of the pins 16 and segments 18 as shown most clearly in Figure at.

To the scraper'frames AandB, and preferably to the angle bars 10 of scrapers 9, I provide eyes 19 to which draft chains 20 are secured, and arrows indicate in Figures 1 and 2, the direction of draft.

The operationis as follows: The scraper frames B and Q aregiven the desiredangular adjustment relative to the main frame A, and the blades 9 are given the desired angular adjustment by means of the levers 1 3 to perform the work necessary and the machine is drawn over the ground or through the ditch in the direction indicated by the arrows in Figures 1 and 3 to scrape the surface, to give the desired angle or pitch and t uniformly surface the road or ditch.

Various slight changes might be made in the general form and arrangement of parts described without departing from my invention, and hence 1 do not limit myself to the precise details set forth, but consider myself at liberty to make such changes and ed on said scraper frames, and means for adjusting the scrapers to various angles relativeto the scraper frame.

2. A machine of the character described, comprising a main frame composed of two sections hingedly connected, a pair of scraper frames adjacent to the respective ends of the main frame, scrapers adjustably mounted on said scra )er frames, concentrically slotted bars fixed to the mainframe, bolts on the scraper frames positioned in said slotted bars, and nuts on the bolts clamping the scraper frames at the'desired angle relative to the main frame.

3. A machine of the character described, comprising a main frame, scraper frames adjustably mounted on the main frame, scraper blades, trunnions on the ends of the scraper blades and pivotally connected to the scraper frames, and means for varying the angular disposition of the scraper blades relative to the scraper frames.

4;. A machine of the character described, comprising a main frame, scraper frames adjustably mounted on the main frame, scraper blades, trunnions on the ends of the scraper blades and pivotally connected to the scraper frames, levers pivot-ally connected to the scraper frames and fixed at their lower ends to the scraper blades, segments on the scraper frames, and means for securing the levers in various positions of adjustment to said segments.

5. A machine of the character described, comprising a main frame consisting of two sections pivotallyconnected, scraper frames at the ends of the main frames, scrapers secured to the scraper frames, angle bars secured to the scrapers, and draft devices secured to the forward outer ends of the scrapers.

6. A machine of the character described, comprising a main frame formed of two rectangular sections hinged together, each section being provided with slotted segments, an oblong scraper frame for each section of the main frame, the said frames being provided in their longitudinal bars with bolts working in the slotted segments and having nuts, a scraper pivoted at its ends in each scraper frame, and means for swinging each scraper, whereby to Vary its angular position.
